Columns in EasyMorph don’t have a fixed type (only cells have).
Most likely numbers which are being quoted are store in EasyMorph as Text
(you can check cell type by right-clicking on a cell and choosing Metadata menu item).
Such numbers are always quoted.
The workaround here is to convert those numbers from Text cell type to Number.
You can do it with Modify column transformation and following expressions:
In case column contains only numeric values:
In case column contains both non-numeric and numeric values:
if(not iserror(asnumber([Column])), asnumber([Column]), [Column])
